Modular suction strainer of low water head loss with the face of the contoured structure

摘要

PROBLEM TO BE SOLVED: To provide a strainer element for an emergency core cooling system which is small enough not to occupy an unduly large area and can prevent excessive head loss from a debris load in the event of a cooling water accident in a nuclear reaction portion.;SOLUTION: An embodiment comprises a strainer element for immersion in a reservoir of cooling water utilized by an emergency core cooling system, the strainer element having at least one major surface with a plurality of perforations therethrough. The cooling water is drawn into the emergency core cooling system through the strainer element. A side of the strainer element in contact with the cooling water has a contoured structure to prevent formation of a flat deposition that may trap particulate material small enough to pass through the perforations.;COPYRIGHT: (C)2014,JPO&INPIT
